Interlocking construction blocks

An interlocking construction block, comprising:

• a first sidewall, comprising:
• a first lower portion;
• and
• a first upper portion integrally connected to the first lower portion, the first upper portion comprising:
• a first plurality of walls;
• and
• a first outer side surface integrally connected to the first plurality of walls, the first plurality of walls tapering inwardly from the first lower portion to the first outer side surface;
• a second sidewall integrally connected to the first sidewall by at least one upper end wall and at least one side end wall, where the at least one upper end wall and the at least one side end wall have a tongue and groove configuration;
• a first reinforcement bar, embedded within the first sidewall, having a first end and a second end extending from a first corner of the block to a first catty corner;
• and
• a second reinforcement bar, embedded within the first sidewall, having a third end and a fourth end extending from a second corner of the block to a second catty corner;
• a base sidewall section integrally connected to the first and second sidewalls, the base sidewall section comprising:
• a front surface;
• and
• a back surface integrally connected to the front surface by a pair of opposing connecting sidewalls and a pair of opposing connecting end walls;
• and
• wherein the first and second sidewalls are located equidistant from the pair of opposing connecting end walls and extend perpendicularly from the base sidewall section;
• wherein at least one of the first, second, third and fourth ends has a generally “Y” configuration having a first Y-end and a second Y-end;
• wherein the first Y-end extends to a first corner of the first sidewall and the second Y-end extends to a first corner of the second sidewall;
• and
• wherein the first and second Y-ends protrude through the first and second sidewalls.
